rthis invention relates to fruit juice extracting devices and more particularlyv to a portable device adapted to be mounted in a kitchen or res-Y taurant or on a soda fountain for extracting juice from fruit, such as oranges, lemons, limes ork whole fruit and cuts it in two as it is squeezed to force the juice therefrom; kwhich vholds the fruit so that juice does not flow over the surface of the fruit and thus protects the juice from possible contamination; which can he operated either by hand or by an electric motor, as may be de# sired; and which is simple and durable in construction, economical to manufacture, effective eiicient in operation, and neat and attractive in appearance.

@ther objects and advantages will become apparent from afconsideration of the following description and the appended claims in conjunction with the accompanying drawings wherein:

base has a V-shaped notch '23 extending inwardly from the side wall past the center thereof and Lprovided-with a rounded inner end and has a angezlextending perpendicularly from the top wall Zoalcng the edge of thenotch 23. The base is provided with apertured bosses 25 and 2G and `the standards Il and it are provided with rcduced endportions 2l and 23 respectively, ex-

`tending through `the boresy of the bosses .25 and 2li externally. screw threaded at their distal ends. lhe annular shouldersl provided at the inner or proximal ends of the reduced end portions. 2'! and ZSof the standards rest upon the top endsof the hossesvz and 2e respectively, and nuts .2e ande!) are .threaded onto the screw threaded portions of .thereduced ends 2l and 28 of the standards and bear against the bottom ends of the corresponding, bosses to .nrmly secure the standards tothe basesothat.thestandards extend upwardly from the base .in spaced apart and .substantially par- 4alici,relationship to each other with their .longi- `.tudinal -.center .lines substantially perpendicular to theplane ofthe vbottoni surface of the base.

The. notchein the base is of a size to receive the bottom portion of a conventional fruit juice .glass .in lthe inner portion thereof.

.Thehstandards H and l2are in the'formof vide 'at their lower v`or proximal ends annular shoulders 33 and 34 on the standards II and I2 espectively. Near their upper ends, the standards are provided with rack teeth, as indicated at 35 and which rack teeth are disposed at the same sides or a plane which includes the longitudinal center lines of both standards.

The head structure I 3 comprises a hollow body including cylindrical flange or skirt 38 and a domed portion 39 joined at its open end to the upper end of the skirt 33 and closing the upper end of the latter, and a dat bottom wall 4Q disposed within the cylindrical skirt S3 at the lower end of the skirt and closing the lower end of the hollow head structure. This bottom wall has a diametrically extending, upwardly curved formation 4I to provide a transversely extending groove in the bottoni wall for a purpose to be later described and is secured to the skirt 39 by the angle brackets 3? spaced apart around the edge of the bottom wall 4S.

The head structure I3 is also provided with sleeve formations l2 and e3 disposed at respectively opposite sides of the head structure and through which the standards Il and I2 extend.

Hollow bosses 44 and i5 are formed on and project upwardly from the bottom wall 4G of the head structure within the sleeve formations 42 and d3 respectively, and slidably receive the end portions 3l and 32 of the standards II and I2 respectively, and the sleeve formations are provided at their upper ends with inwardly flange apertures and d? through which the upper ends or" the standards can project when the head str cture is moved along the standards toward the base It.

Bearing blocks dil and 49 are formed on the bottom wall 49 and project upwardly from the bottom wall adjacent the inner sides of the sleeve formations 42 and 43 respectively, and these bearing blocks are provided near their upper ends with apertures which respectively receive bearing bushings S and 5l.

A shaft 52 extends transversely of the head structure i3 and through the bearing bushings 5G and 5l in which it is journaled. This shaft is provided with gear teeth adjacent its opposite ends, as indicated at 53 and 54, which gearteeth mesh with the rack teeth 35 and 33 on the standards II and I2 to move the head structure longitudinally of the standards toward and away from the base when the shaft 52 is rotated.

A third bea-ring block 55 is provided on and extends upwardly from the bottom plate 4) between the bearing blocks 48 and 49 and is provided in its upper end with an aperture receiving a bearing bushing 5l', while a fourth bearing block 58 extends upwardly from the bottom wall fill adjacent the boss l5 and is provided near its upper end with an aperture receiving a bearing bushing ES. The bearing blocks 5G and 58 are shorter than the blocks llt and 49, and a shaft 5D extends through and is journaled in the bushings 5l and 59 carried by the blocks 56 and 58. The shaft SG is spaced from and substantially parallel to the shaft 52 and has one end extending outwardly of the head structure and its other end adjacent the bearing block 58 provided with gear teeth 6I.

A gear 62 is mounted on the shaft 52 between the bearing blocks 48 and 4S and has its teeth in mesh with the gear teeth 5I on the inner end 0f the shaft lill and the handwheel I4 is mounted on the end of the shaft @il projecting outwardly of the head structure I3 and provided on its outer side with a hand knob 63.

With this arrangement, when the handwheel I4 is rotated by the knob G3 the shalt 9 will be rotated and drive the shaft Rotation of the shaft 52 by the engagement of its gear or pinion teeth 53 and EQ with rack teeth 555 and 3C. on the standards will move the head structure longitudinally of the standards tor-,fard or away from the base It depending upon the direction of rotation of the handwheel As the gear G2 is materially larger than the gear formation on the inner end of the shaft to, a mechanical leverage is provided to increase the downward force exerted on the head structure by rotation of the handwheel.

The dished plate l5 is o1" generally circular shape and is secured to the end wall of the head structure at the noch1 of the end wall by suitable means, s'- h he clips G5 which are secured to the end wall fli and margin f engage the plate ES, and this plate laces y down wardly and has a transversely e` slot SG therein disposed in alignment groove formation 4I in the bottoni plate ol the head structure.

The bed structure IE includes a cylindrical skirt portion 6- having an inwardly directed flange at its upper end and having sleeve formations 'i6 and 'II at respectively opposite sides thereof through which the reduced' end portions 5I and 32 of the standards extend. These sleeves are provided in their upper ends with boss forniations l2 and i3 respectively, which slldably receive the standard portions 3l and 32 and provide annular shoulders "Je and l5 at their bottom ends.

A bracket Y6 is provided at one end with a boss formation 'il receiving the portion 3i ci the standard Il and resting upon the shoulde' 33 at the lower end of the standard portion I and with an arm 'iE extending from the boss formation 'il toward the standard f2 and provided near its distal end with an aperture 'i3'. A similar bracket is provided with a b formation GI receiving the portion and resting upon the annular shoulder 3l of the standard l and with a laterally extending arm which rejects from the boss formation toward the stamm-d l i and is provided near its distal end .lith an apert E".

A coiled compression spring S5 surrounds the standard ll between the upper end of the boss formation l? and the annular Shoulder 'lli in 'he sleeve formation and a corresponding c compression spring E5 surrounds the .Standard l between the upper nd of the boss formation 3 and the annular shoulder 'lll in the sleeve formation lI. These springs support the bed structure l5 on the standarde for limited freedom of resiliently resisted movement of the bed structure toward the base of the device.

A post 88 has a reduced lower end received in the aperture in the bracket arm 'i8 and extends upwardly frorn the bracket arm, while a similar post 89 has a reduced lower end received in the aperture 83 in the bracket arm 82 and extends upwardly from this bracket arm. The posts 8B and :'59 are disposed in spaced apart and substantially parallel relationship to each other, and the blade I8 extends between the posts 88 and 89 and is secured at its respectively opposite ends to these posts.
